LS Oil Galley Plug Billet Aluminum

The ALLSTAR PERFORMANCE LS Oil Galley Plug Billet Aluminum is a precision-engineered component designed for LS engine builders and performance enthusiasts. It plays a crucial role in sealing the oil gallery passages, preventing coolant and oil cross-contamination while ensuring proper fluid pressure distribution throughout the engine block.

Manufactured from high-quality billet aluminum, this plug offers superior material consistency and dimensional accuracy compared to cast alternatives. This construction reduces the risk of porosity-related failures under high RPM conditions and provides excellent machinability for custom applications. The tight tolerances help prevent oil weeping at the gallery interface, enhancing engine reliability.

Ideal for those performing a complete LS head reseal or assembling an engine from a bare block, this plug is essential for maintaining engine longevity and consistent oiling system function. Proper installation with the correct torque specification and thread sealant application is recommended for optimal performance.
